Excaliber, on the other hand, very much expect us and have space already laid out simply because it's run by the same people that let us have all that space at Gen Con UK. It's a small holiday camp-based convention, I'll be doing cookies and unless you're very nice to me, Secret Midnight Cthulhu. The organisers' site is at http://www.horsemenevents.com/ and the details for the con can be found there (in theory; I have a devil of a job negotiating the site myself).
Now, I'd better find what I've done with the stash of Treehouse dice I've been making up....
